"How much should it cost to land on Mars?"

Academician She: "If we do it ourselves and make full use of the space station in lunar orbit or low earth orbit to accelerate, it is conservatively estimated to be about 80 billion to 100 billion yuan; However, if the traditional spacecraft is used to land on the moon, it is not much different from the moon landing in terms of technology, and it cannot produce as much scientific and technological impact as the moon landing to promote technological and economic development. ”

Although the Dawning Plan was launched in a hurry, it injected a huge amount of funds, mobilized the strength of almost all scientific research institutes and universities across the country, and absorbed the power of private aerospace under the control of the Aviation Development Commission.

If you really want to say that the number of people participating in the Dawning Project may exceed millions, the scale of enterprises involved has reached tens of thousands, and it has led to quite a lot of technological breakthroughs.

Liuyuan's imitation of Xinyuan and specaX's engine streamlined production has greatly reduced costs and increased production to a level that was unimaginable in the past.

As a result, the supporting subordinate factories have ushered in technological upgrades and specification updates, which are also beneficial to the manufacturing of other products.

Another example is the development of the lunar rover, which was also contracted to two private enterprises to develop new batteries and special motors, and these expensive technologies will eventually be civilianized to gain advantages for their products and earn back research and development costs.

Not to mention the countless scientific research groups composed of universities and research institutes, all of which are participating in various ways.

For every $1 invested in astronautics, $7 to $12 can be recovered in other areas is not fake, but it is also conditional.

The moon landing can bring technological upgrades, but landing on Mars is different, the technology used in the traditional method is no different from the moon landing, there is no scientific research dividend, it is purely about spending money.

Therefore, for Huaguo's manned landing plan, both the space agency and the superiors are really not in a hurry, and it is not so important to see it.

The resources of the moon are abundant enough, the population pressure on the earth has not yet exploded, and the significance of a manned landing on Mars is not small in spirit, but not large enough in material.

Academician She continued: "In the past, we envisioned that we would complete the manned mission in the middle of this century, complete the moon landing in the 30s, and spend 20 years preparing to keep the investment low; Now, if preparations start in 20, it will be possible to land on Mars by almost 2030;

In this way, the cost is much lower, ten years, an average of three billion yuan per year in this direction is enough, due to the technological breakthrough of the moon landing, it may not be as much as the Dawning program in the end. ”

Superior: "Mars is different from the Moon, it is more scientifically exploratory. ”

Academician She pondered the meaning of this sentence for a moment, and then suddenly realized.

Scientific exploration is more meaningful, which does not mean that there is no need to fight or grab, but that there is no need for the space agency to work alone.

The superior has taken a fancy to the Advance space station!

He could understand why his superiors had been silent after seeing the plan to advance the space station, and the latter's idea might be that they wanted to use the power of Xinyuan Company to jointly land on Mars.

What is correct about landing on the moon first, just thousands of years of Chinese people's longing for the moon does not allow the space agency to lag behind, but Mars is different, it is not as close as the moon in front of you, there is no special complex.

Moreover, the investment is very huge and the return is low, and it was previously envisioned that it would be difficult for a single country to do so, and that it would require the cooperation of several space powers in the world.

In this case, it is nothing to pull down to private enterprises, anyway, the space agency has landed on the moon, it is impossible to carry out it alone because of technical factors, as long as the Chinese people can land on it with their own strength.

"Xinyuan seems to have made a part of the cabin? We don't necessarily have to join the forward space station, but we can try to participate in the construction of the subsequent modules, they are not always, right? Master some technology, and when the time is right, Huaguo will also develop its own centrifugal space station. ”

When is the right time?

Academician She knew that this time would not be too long, and he couldn't help but get excited at the thought of building a centrifugal space station with the power of the country.

"Then I'll ask, but they already have subordinate factories of the space agency in their supply chain, and they should have been involved, but they don't know it."

Superior: "Good, by the way, you don't know the ternary computer?" I've received quite a few reports. ”

Academician She: ?

……

Three days ago, in Beijing, Beijing Navigation Software Company, four employees hugged cardboard boxes, greeted their former colleagues and bosses with a smile, and then got into the business car waiting outside early.

Jinghanger, formerly known as Beijing University of Aeronautics and Astronautics, was established by the promotion of Beijing University of Aeronautics and Astronautics, and the most famous product their company has made is called CAXA.

In the field of modern industrial design, the most important and basic part is electronic drawing.

CAD, Computer Aided Diagnosis, computer-aided design, was first born in the 60s of the last century Boeing's independent plan to improve the efficiency of drawing, in 1982, Aramco appeared the world's first CAD software: AutoCAD.

Any part drawings, assembly drawings, processing drawings, and then up to 3D modeling, simulation, need to be applied to these industrial software.

Aramco's AutoCAD, CATIA developed by Dassault Systèmes, solidworks, Siemens' NX, Huaguo's CAXA, and ZWCAD are all mainstream and well-known CAD software.

This is the basis of modern machinery manufacturing, without CAD software there is no complex CNC machining, there is no mass production of complex parts.

Ordinary people or small factories with only a few people can easily find pirated CAD software to use, but for a small scale, especially a formal enterprise, it is necessary to use genuine versions.

In order to make a profit, software companies have built complex anti-piracy mechanisms into their CAD software, such as automatic networking, copyright certificates, activation codes, etc., and set up agents for each region.

Agents stare at those manufacturing-related companies all day long, and then look for what kind of CAD software they use, and if it is their own piracy, they will immediately come to the door to defend their legal rights.

For regular manufacturers, if the products developed by using pirated software are all infringing and are not protected by the laws of various countries, they will generally spend money to buy genuine copies.

Software manufacturers are not philanthropists, the purchase of CAD software is not once and for all, each set of software only provides a period of one to a few years, expired to renew, of course, software manufacturers also have to bear the responsibility of software maintenance, experience improvement and so on.

Xinyuan spends hundreds of millions of yuan every year to buy various industrial software usage costs, even including Windows, all of which are thousands of sets of Windows7 professional edition CDs.

Last year, Jinghaier's CAXA series software was purchased by Xinyuan for thousands of sets of two-year licenses, so that the company made a lot of money, but I don't understand why I only bought it for two years, is it because the agent price is too high, and I want to change to other homes?

It doesn't exist, Xinyuan is not just buying one, each product has a different focus, and domestic and foreign software are used.

As a result, in recent months, Beijing Navigation has found that the number of employees who have left the company is increasing, and many of them are old employees.

It looks like Xinyuan Aerospace is planning to develop its own CAD software? But not to mention the cost of redevelopment, software patents alone can't be bypassed.

CAD software in various countries has been developed for so many years, windows, linux, and even DOS systems are involved, and a patent wall that can be airtight has long been formed.
